UNITED STAT S JOHN CARSON, OF HAMILTON, DAKOTA TERRITORY.

SEEDEFL SPECIPICATION forming part of Letters Patent No. 372,743, datedNovember 8, 1887.

-Application filed August 15, 1887.

.To aZZ whom it may concern:

Be it known that I, J 011x CARSON, a citizen of the United States ofAmerica, residing at Hamilton, in the county of Pernbina and Territoryof Dakota, have invented certain new and useful Improvements inGrain-Drills; and I do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same.

This invention pertains to certain new and useful improvements ingrain-drills, having for its object to provide simpleand efficient meansfor increasing the distribution of the seed and to permit the drill toconform to any unevenness of the ground; and the invention consists inthe detailed construction, combination, and arrangement'of the parts,substantially as hereinafter fully set forth, and particularly pointedout in the claims.

In the accompanying drawings, Figure l is a plan view of my invention.Fig. 2 isaside View thereof. Fig. Sis a front elevation. Fig. 4 is avertical transverse section on the liners m, Fig. 1; and Fig. 5 is adetail sectional view.

Corresponding parts in the several figures are denoted by the sameletters of reference.

This improvement consists, essentially, of two distinct seeders ordrills connected with each other and additionally supported by a thirdcentrally-disposed carrying-wheel, the same being rigidly connected onthe inner end of the axle of the carrying-wheel of one of the seeders ordrills, from which axle motion is transmitted to the ordinary agitatingmechanism of each seeder or drill, all of which will now be fullydescribed.

Referring to the drawings, A A represent two long horizontally-disposedframes of a seeder or drill composed each of two longitudinal bars, ac,to the ends of which are connected forwardly-projecting bars a a, havingfront connecting-bars, a at. These front connecting-bars, a a, areextended a short distance beyond the inner opposite bars, a a, of eachseeder or drill frame, and are suitably hinged or otherwise connectedtogether, as

' shown at a, Fig. 1.

The seeder or drill frameA is supported at Serial No. 246,965. (Nomodel.)

its outer end by a carrying-wheel, B, the axle of which is suitablysecured in boxing of or dinary construction disposed between thelongitudinal bars a a of said frame, as clearly shown in Fig. 1. Theseeder or drill frame A has likewise'secured to its outer end a wheel,B, the axle b of which projects longitudinally through the frame A andextends a short distance beyond the innerendthereof, and on this end ofthe axle is rigidly secured a third central carrying-wheel, B, the samebeing designed to rotate within the space formed between the inneropposite bars, a, of the seeder or drill frames A A. This projecting endof the axle b has also secured thereon apinion or gear-wheel, C, workingin an approximately oblong slot or opening formed in the center of abox, 0, also secured on said end of the shaft, the same, together withthe pinion, being retained in proper position by means of a nut, I),screwed on the end of the axle and bearing against the side of said os'cillating box, as shown. The narrowed projecting ends of this box 0 havesleeves 0* adapted to oscillate therein, said sleeves being fitted insuitable openings or apertures, formed in the projecting ends of thelongitudinal bars a a of the seeder or drill frameA, as shown.

On the axle b,within the frame A, is rigidly secured a small pinion orgear wheel, b, similar to the pinion or gear-wheel 0 above referred to.From these pinions or gearwheels G b motion is transmitted (by reason ofthe turning of the axle b) to the seed or grain agitating mechanismdisposed within the ordinary hoppers designed to be suitably secured onthe frames A A; but as these features form no part of my invention,further reference thereto or any illustration thereof is not necessary,the same being of any ordinary construction.

It will be understood, of course, that theseed o'r grain hoppers abovereferred to are, as customary, provided with the usual drills. and pipesor tubes for conveying the grain from said hoppers. v

E E are two parallel forwardly-projecting bars having rear hooked endsdesigned to engage with eyes or apertured ends of two bars or straps, E,secured to the under side of the longitudinal bars a at about the centerthereof. These parallel bars E are connected at their outer ends and attheir centers by cross-bars e e, the same extending parallel with thefront connecting-bars of the frames A A. To the center of thesecross-bars e is connected the central tongue or pole, e as shown inFig. 1. The parallel bars E E are secured in position against the underside of the front connectingbars, a a, by means of stirrups e e, thesame being sufficiently large to permit of the free movement of saidbars, occasioned by the vibration of the hoppers and frames, said barsbeing rounded at the points where passed through the stirrups to enablethem to readily move, as stated.

To the tongue or pole 6 at a point about midway the cross-bars e, isseen red aplate, F, having at its rear end two apertured ears or lugs,ff, to which are connected the forward ends of two similarly-constructedrods, FF, which rods extend rearwardly in opposite directions, and aresecured to suitable staples at the center of each seeder or drill frameA A. These rods F are slightly bent or upwardly curved where passed overthe front connecting-bars of the frames A A and the central cross-bar,0, so as not to interfere with the upward and downward movement of thesaid seeder or drill frames.

From what has been said it will be seen that my invention provides forincreased distribu' tion capacity by the employment of two distinctseeders or drill frames for supporting the hoppers and distributingmechanism; that the same are properly supported and carried at theirinner opposite ends by a central carrying-wheel; and that by means ofthe oscillating box-connection between the axle of one frame and theends of the longitudinal bars of the other frame, and the connectionbetween the front connectingbars, the two frames are permitted to have afree vibratory motion, the connections with the tongue or pole being soarranged as not to interfere therewith, as pre= viously stated.

I claim as my invention 1. The combination, with the two seeder or drillframes, of the third central carrying wheel secured on the projectingend of the axle of one carrying-wheel and having a boxconnection withone of said frames, substantially as shown and described.

2. In a grain-drill of the class herein described, the combination, withthe frames and their carrying-wheels, of the central supporting-wheelsecured upon the axle of one of said carryingwheels, the box-connectionbetween one end of said axle and the adjoining frame, and thehinge-connection between the front cross-bars of said frames,substantially as shown and described.

3. The combination ofthe two frames having the two longitudinal bars,the carrying-wheels having their axles projected between said bars, thethird carryingwheel supported upon the inner end ,of one of said axles,the box-eonnection upon said axle, and the hinge-connection between thefront connectingbars of said frames, substantially as shown anddescribed.

4. The combination, with the seederor drill frames having their frontcrossbars connected together, of the central carrying-wheels, theforwardly-projecting parallel bars connected to said frames, thecross-bars, the tongue or pole, and the rods having curved portions,substantially as shown and described, said par allel bars being passedthrough stirrups of the front bars of said frames, as stated.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN CARSON.
